Created attachment 363582 [details] emerge --info I had upgraded gcc from 4.6.3 to 4.7.3 a short while ago. A package I'm trying to build has crypto++ as a dependency, but the ebuild fails when it tries to pull in libraries from /usr/lib/gcc/x86_64-pc-linux-gnu/4.6.3/../../../../lib64/ (never mind that this is really just /usr/lib64/).
Created attachment 363584 [details] emerge -pqv
Created attachment 363586 [details] build.log
This workaround will allow crypto++ to build: cd /usr/lib/gcc/x86_64-pc-linux-gnu && ln -s 4.7.3 4.6.3
gcc-config -l gcc-config <new version> . /etc/profile <do your thing>
